Severe stability and clock issues with non-current ROS. Works like a top on 3.19 though. Also, if using an SATA-to-CF converter, the license key for the CF card in an R200 will only transfer to other R200's without Mikrotik reissuing it.

works in RouterBOARD 411U with miniPCI-e slot and SIM slot. Set data channel and info channel to 3. Performance on CZ O2 in Prague HSDPA connection about 2.6Mbit download and 0.7Mbit upload. Latency between 100-300ms. Application based on this on http://carlive.cz[10]. UPDATE: connection freezes sometimes, reboot of routerboard doesn't help, it's needed to disconnect from power supply and reconnect again to get it working.
